Answer:
y=3x+8
Step-by-step explanation:
Perpendicular to -1/3, is 3.
y-5=3(x+1)
y-5=3x+3
y=3x+8
Answer:
y - 5 = 3(x + 1).
Step-by-step explanation:
y = -1/3x - 6
The slope of this line is -1/3 so the slope of the perpendicular line to it is -1/-1/3
= 3.
Using the point-slope form of a straight line:
y - y1 = m(x - x1) where m = the slope and (x1, y1) is a point on the line:
Here m = 3 and (x1, y1) is (-1, 5) so we have:
y - 5 = 3(x - (-1))
y - 5 = 3(x + 1).

Answer:
Option D
Step-by-step explanation:
Area of trapezium = sum of 2 parallel sides × height / 2
Here the two parallel sides are = 8 in. and 12 in.
And height = 7 in.
∴ Area of the trapezium = ( 8 + 12 ) × 7 / 2
= 20 × 7 / 2
=70 in^2

what is the measure of x? 68 degrees 70 degrees
Answer:
x = 138°
Step-by-step explanation:
Since the sum of all angles in a triangle is 180°, we find ∠BAC:
m∠BAC = 180 - (68 + 70) = 42°
Since ∠x and ∠BAC are Supplementary Angles, they add up to 180°:
180 - 42 = x
x = 138°
Answer:
138
Step-by-step explanation:
1. 68 + 70 = 138
2. 180 - 38 = 42
3. 180 - 42 = 138
4. X = 138

Please please help!!! Study the diagram of circle Z. Points P, O, Q, and R lie on circle Z in such a way that OP¯¯¯¯¯¯¯¯≅QR¯¯¯¯¯¯¯¯. If m∠QZR=(2x+9)∘ and m∠PZO=(4x−11)∘, what is the value of x?
x=3.3
x=15.3
x=10
x=12
Answer:
The correct option is
x = 10
Step-by-step explanation:
in a circle Given that chord [tex]\overline {OP}[/tex] is congruent to [tex]\overline {QR}[/tex], we have;
Measured angle m∠RZQ is congruent to measured angle m∠PZO
Congruent chords are subtended by congruent angles at the center of the circle
Therefore we have;
4·x - 11 is equal to 2·x + 9
4·x - 2·x = 9 + 11
2·x = 20
x = 10
The value of the measured angles are;
4·x - 11 = 4×10 - 11 = 40 - 11 = 29°
The value of x is 10°.
Answer:
x=10
Step-by-step explanation:
4·x - 11 is equal to 2·x + 9
4·x - 2·x = 9 + 11
2·x = 20
x = 10
The value of the measured angles are;
4·x - 11 = 4×10 - 11 = 40 - 11 = 29°
The value of x is 10°

Answer:
67 degrees.
Step-by-step explanation:
The two quadrilaterals are congruent, with angle T corresponding to angle F, angle U corresponding to angle C, angle V corresponding to angle D, and angle W corresponding to angle E.
A quadrilateral's interior angles add to be 360 degrees.
x + 138 + 67 + 88 = 360
x + 293 = 360
x = 67
So, angle D is 67 degrees.
Hope this helps!
are the triangles similar?
Answer:
Yes.
Step-by-step explanation:
The angles of the triangles add up to be 180. 180 - 114 - 31 = 35. 180-114-35 = 31. Since the angles of the triangles correspond and are congruent, the triangles are similar, with PQR corresponding to TUS.

Flying against the wind, an airplane travels 7520 kilometers in 8 hours. Flying with the wind, the same plane travels 6500 kilometers in 5 hours. What is the rate of the plane in still air and what is the rate of the wind?
Answer:
Rate of plane in still air = 1120 km/h
Rate of wind = 180 km/h
Step-by-step explanation:
Let the rate (speed) of the plane in still air = u km/h
Let the rate (speed) of the wind = v km/h
Formula for speed is:
[tex]Speed = \dfrac{Distance}{Time}[/tex]
Given that against the wind, airplane travels 7520 km in 8 hours.
The speed against the wind will be slower so,
Against the wind, speed = (u -v ) km/h
Using above formula:
[tex](u-v) = \dfrac{7520}{8} km/h\\(u-v) = 940 km/h ..... (1)[/tex]
Given that with the wind, airplane travels 6500 km in 5 hours.
The speed with the wind will be faster so,
With the wind, speed = (u +v ) km/h
Using above formula:
[tex](u+v) = \dfrac{6520}{5} km/h\\(u+v) = 1300 km/h ..... (2)[/tex]
Adding (1) and (2) to solve for u and v:
[tex]2u = 2240\\\Rightarrow u = 1120\ km/h[/tex]
Putting u in (1):
[tex]1120-u=940\\\Rightarrow u = 180\ km/h[/tex]
So, the answers are:
Rate of plane in still air = 1120 km/h
Rate of wind = 180 km/h

Open the graphing tool, and compare the functions using the sliders. What can be said about the domain of
y= VX - kand the domain of y = VX + k?
Answer:
Therefore, domain of y = [tex]\sqrt{x-k}[/tex] ; Domain = [k, ∞)
Domain of y = [tex]\sqrt{x}+k[/tex] ; Domain = [0, ∞)
Step-by-step explanation:
Two functions are,
y = [tex]\sqrt{x-k}[/tex]
and y = [tex]\sqrt{x}-k[/tex]
Let the value of k = 1
Then we find the graph of the functions attached.
By analyzing these graphs,
y = [tex]\sqrt{x-1}[/tex] when shifted 1 unit right and 1 unit down we get a new function,
y = [tex]\sqrt{x}+1[/tex]
Therefore, domain of y = [tex]\sqrt{x-1}[/tex] ; Domain = [1, ∞)
Domain of y = [tex]\sqrt{x}+1[/tex] ; Domain = [0, ∞)
Similarly, domain of y = [tex]\sqrt{x-k}[/tex] ; Domain = [k, ∞)
And domain of y = √x + k ; Domain = [0, ∞)

Which of the following is an arithmetic sequence?
Answer:
B
Step-by-step explanation:
An arithmetic sequence there will be a constant difference between terms.
Option A: this sequence is not an arithmetic sequence as the difference between the 1st term and the 2nd term is ×[tex]\frac{1}{2}[/tex], but the difference between the 3rd term to the 4th term is ×[tex]\frac{1}{4}[/tex].
Option B: this sequence is an arithmetic sequence as the differences between every two consecutive terms are +5.
Option C: this sequence is not an arithmetic sequence as the difference between the 1st term and the 2nd term is -8, but in the difference between the 2nd term and the 3rd is +8.
Option D: this sequence is a typical fibonacci sequence, and clearly we can see that the differences are different in every two consecutive terms.

Definition:A sailboat set a course of N 25° E from a small port along a shoreline that runs north and south. Sometime later the boat overturned and the crew sent out a distress call. They estimated that they were 12 miles away from the nearest harbor, which is 28 miles north of the port they had set sail from. If a rescue team leaves from the harbor, find all possible courses the team must follow in order to reach the overturned sailboat.
Answer:
S 75°E
S 55°E
Step-by-step explanation:
Take the law if sines of a triangle:
[tex] \frac{a}{sinA} = \frac{b}{sinB} = \frac{c}{sinC} [/tex]
Where,
a = 28 miles
B = 25°
b = 12 miles
First solve for A, using the law of sines:
[tex] \frac{a}{sinA} = \frac{b}{sinB} [/tex]
[tex] \frac{28}{sinA} = \frac{12}{sin25} [/tex]
Cross multiply:
[tex] 28 sin25 = 12 sinA [/tex]
[tex] 11.83 = 12 sinA [/tex]
[tex] Sin A = \frac{11.83}{12} [/tex]
[tex] Sin A = 0.986 [/tex]
[tex]A = sin^-^1(0.986)[/tex]
[tex] A = 80.44 degrees [/tex]
Since A = 80.44° find A supplement, A`:
A` = 180 - 80.44
A` = 99.56°
If A` + B < 180°, find C.
Thus,
A` + B = 99.56 + 25 = 124.56
We can see that A` + B < 180
Find C:
C = 180 - (80.44+25) = 74.56° ≈ 75°
C` = 180 - (99.56+25) = 55.44° ≈ 55°
Rewrite in bearing form:
S 75°E
S 55°E

A linear function has the same y-intercept as x + 4y = 8 and its graph contains the point (4, 3). Fill in the blank to find the y-intercept.
Answer:
The y - intercept is (0, 4)
Step-by-step explanation:
The equation x + 4y = 8 is in 'standard form.' Any line parallel to this line has an equation that looks exactly the same EXCEPT for the constant.
So, let's write out x + 4y = 8 and replace the 8 with C.
x + 4y = C
Now take the coordinates of the given point (4, 3) and substitute them into the above equation: 4 + 4(3) = C = 16
Thus, the equation of the line passing through (4, 3) is x + 4y = 16.
To find the y-intercept, set x = 0 and calculate y:
0 + 4y = 16, or y = 4
The y - intercept is (0, 4)
